MECHANISM FOR REMOVING CONES FROM MOLDS AND TRIMMING SAME. I

aeaaoeo.

Be it known that I, ALBERT E. DnrrERIoH,

residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Mechanism for Bemoving Cones from Molds and Trimming the Same, of which the following is a specification.

themagainst following the female mold sections as the said sections continue separation for the purpose of releaslng the cone from the molds and from the holding device,

and thirdly, a method of extracting the cones from the molds, which method consists in holding the cones against movement during the initial part of the opening act of the female molds to strip the cones loose from the moving parts of the female molds andv subsequently holding the cones while the prior holding device is separated from the cones and then removing the cones from their location between the female mold parts.

The female mold sections of the mechanism referred to have separable parts, certain of which ,open up in advance of the others, the latter serving to hold the cones stationary while the former separate from the cones during the initial opening movement of the molds, but which latter devices separate or leave the cones as soon as the receiver has been projected between the initially sepa} rated parts of the female molds to embrace the cones and restrain them from following the mold parts when" completing the opening and releasing 'act.

My invention relates especially to the machine such as contains the structure, aforesaid, and it has for its object to provide a modification of the said mechanism whereby all danger of breaking the cone in freeing it from the last-tosopen-parts of the female molds, is avoided. Another object of my invention-is to provide a trlmmlng'mechamsm Specification of Letters Patent.

with stationary trimmer tubes, as in the Bruckman type of machine (see Patent #-l,071,027, of' August 26, 1913, for example) with which thefinvention is espe-- cially useful, and to provide a positive means for conveying or lowering the cone from the female mold region into the trimmer tubes whereby each individual cone will be positively set into its respective trimmer tube member in a position ready for the pusher, which forces the cone through the tube to trim of]? the excess batter or heads.

Generically, then my invention comprises a reciprocated receiver that'moves through the trimmer tubes up between the partly separated female molds and snugly embraces the exposed part ofthe cone and when the female molds are fully open the receiver descends again through the trimmer tube leavmg the cone hanglng in the trimmer tube Patented Nov. 20, 1917.

Application filed February 16, 191?. Serial No. 149,051.

by its excess batter-head, after which it is I pushed through the tube either by a pivoted pusher (as hereinafter shown and described) or by the shuttle type of pusher that forms the subject of my Patent No. 1,216,292, issued February 20, 1917.

More subordinately, the present invention includesa receding chute that is-located below the trimmer tubes and above the receiver, by which chute the trimmed cones are shot to the off-take conveyer (not shown) of the machine, the receding chute member being adapted to be moved out of the way automatically by the receiver as the receiver is raised and passes through itsactive cycle of movement.

The invention also includes those novel details of construction, combination and arrangement of parts, all of which is first fully described, then specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a section and part elevation illustrating the invention.

Fig. 2 is a transverse vertical section taken substantially on the line 22 of Fig. 1, the core being shown in place and a baked cone ready for delivery from the molds, the trimmer mechanism and the receiver mechanism being in the inactive position. Fig. 3 is a view similar to Fig. 2 showing the position of the parts just after the receiver has been moved up to embrace the cone after the female molds are partly open and before the final opening movement has occurred, the core being indicated as withdrawn.

In the drawings, in which like numerals and letters of reference indicate like parts in all of the figures, 1 represents the rotary wheel (when the invention is used in the Bruckman type of machine) on which the arms 2 that support the female mold halves 3 are located, it being understood that the arms 2 in the Bruckman type of machine are pivoted to open the female mold sections with a pivotal movement. Each fe male mold section includes the matching half-cone cavities 4 and they also support the oven sides 5, the oven being covered by a top 17 carried bythe core members 16 that are secured to the core bar 18.

In the prior construction, before referred to, the female mold cavities are recessed, as at 6, to receive ring-like holders that embrace the mouth of thecone and their inner surfaces form a continuation of the molding surfaces of the molds'when the parts are in the normal or closed position. The halfring members 7 are respectively mounted on bars 9 that operate through slots 8 in the female mold sections and have collars 10 between which and bearings 12 coil springs 11 are located to continuously tend to force the rings 7 together, the bearings 12 being carried on brackets 15 that are secured to the wheel frame 1. 13 are collars and 14 are stop pins whereby the movement of the rod 9, under the influence of the spring 11, is'limited.

19 designates the trimmer tubes of which there is one tubular section for each mold cavity of the female molds and the trimmer tubes 19 may be, per se, of any approved construction. They are mounted on brackets 20 which connect the vertical channelways 23 with the standards or supports 21, the supports 21 and the channelways 23 bein bracketed to the connecting ring 22 on whicl a the mold opening and closing cams (not shown) are usually mounted. 24 is another brace securing the guideway 23 to the standard 21 and also serving to support standards 29 in" which the chute section supporting rock shaft 30 is journaled, the rock shaft 30 carrying arms 31 which are moved in one direction by spring action 32 and which are connected by members 33 with the yieldable chute section, the section 34 fitting into the upper stationary section 26 that is secured at 27 to brackets 25 pendent from th trimmer tube unit and the yieldable section 34 of the chute also engages the lower fixed section 28 which is secured at 28 to the standards 21.

35 i the arm of the pusher which is pivoted at 36 and carries thetube engaging member 37, the arm being connected by a rod 40 with the bell crank 38, the latter being pivoted at 39 and adapted to be operated by a quick-throw-cam 41 on the cam shaft 42.

43 is a reciprocating frame having guides 44 operating in the guideways 23 and supporting tubular bodies 45, one for each molding section, the tubes 45 having conical receivers 46 at their upper ends and being of a diameter to pass through the respective trimmer tube sections 19 and enter between the partly open female mold (see Fig. 3) to receive the cone just prior to the release of the same, as the rings 7 open up. I

The frame 43 may be reciprocated by any approved type of mechanism, such for instance, as that shown in the drawings, and this mechanism comprises a support 47' on which is fulerumed a long lever 48 that has a pin and slot connection 49 with the frame 43.

. 50 is a stud on which a lever 51 is fulcrumed and has a pin and slot connection 52 with the lever 48. 53 is an arm fulcrumed on the lever 51 and having a recess 56 for the roller 55 on the end of one arm of the bell .crank 54, which is also pivoted on the stud 50 and is springconnected at 57 with the arm 53, the construction being such that in the event that the frame 43 is obstructed in its movement, no motion will be imparted to the lever 48 by the rocking of the bell crank 54, as the end 55 of the bell crank will ride out of the recess 56 against the spring tension 57 and the lever 48 be prevented from moving. The bell crank 54 is operated by a cam 58 on the cam shaft 42. v

In operation, assume the parts to be positioned as shown in Figs. 1 and 2: the mold having arrived at the extraction ordelivery station, and the mold openin devices, (not shown) just about to begin opening. As soon as the female mold sections have opened to the extent indicated in Fig. 3, the cam 58 will have rocked the bell crank 54 to raise the lever 48 and thus elevate the frame.

As the, upper ends 43 with the tubes 45. of the tubes 45 engage the yieldable chute section 34, it will be swung to the position shown in Fig. 3, and the tubes 45 will pass through the trimmer tubes 19 to bring the receivers 46 into position between the partly separated female molds and around the cone therein, as clearly shown in Fig. 3 of the drawings. As soon as the ring members 7 are separated by the further opening of the female molds, which occurs immediately after the tubes 45 have reached the position indicated in Fig. 3, the cone will be released from the rings 7 and held in the receiver 46, which, immediately the release of the cone from the ring 7 is effected, returns to the position shown in Fig. 2, thus leaving the cone hanging by the excess batter or head (see dotted lines Fig. 2) in the trimmer tube. As soon as the receiver 46 hasreached the position shown in Fig- 2, the cam 41 will rock the bell .crank 38 to bring the pusher head 37 down on the cone and force it through the trimmer tube 19, whereupon it drops onto the chute and is conveyed'to the off-take mechanism, the pusher then being restored to its initial position by the action of the spring In this application, I make no claim to the construction of the molds, per se, nor to the broad combination of such molds with a receiver that is designed to enter between the partly open female molds for'the pur-- pose of holding the cone while the rings 7 separate, as that forms the subject-matter of the application of Alexander McLaren, hereinbefore referred to, nor do I lay any claim, per se, to the particular mechanism shown for raising and lowering the frame 43, as that mechanism, per se, forms a part of the mechanism for operating core greasers in the patent of Frederick A. Bruckman, granted December 1, 1914, No. 1,119,239.
